The disclosure is directed to a method used by a UE to preconfigure a resource for small data transmission in an inactive state and a user equipment using the same method. In one of the exemplary embodiments, the disclosure is directed to a method used by a UE to preconfigure a resource for small data transmission in an inactive state. The method would include not limited to: receiving a CG configuration which is for a small data transmission before entering an inactive state; verifying a CG resource of a camping cell associated with the CG configuration by determining whether the camping cell satisfies a validation condition before triggering a SDT procedure, wherein the CG configuration comprises a list of CG configurations associated with a list of cells; and utilizing the CG resource for the SDT procedure when the validation condition has been determined as being satisfied.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method of claim 1, wherein each CG resource configuration of the list of CG configurations comprises a CG resource set to be used for a SDT.
3. The method of claim 1, wherein each CG resource configuration within the list of CG configurations comprises a CG-CofigSchedule information used for scheduling a CG resource.
4. The method of claim 3, wherein each CG resource configuration of the list of CG resource configurations is associated with the CG-CofigSchedule from which the CG resource is acquired-.
6. The method of claim 5, wherein in response to the CG resource being valid as the verification condition is satisfied, a CG resource configuration is acquired before performing the SDT.
7. The method of claim 6, wherein the CG resource configuration is acquired from the CG-CofigSchedule before performing the SDT in response to the CG resource being valid.
8. The method of claim 1, wherein the validation condition further comprises whether the CG resource of the camping cell is valid.
9. The method of claim 8, wherein the whether the CG resource of the camping cell is valid is determined according to a reserved CG resource status for a SDT (CG-SDT) which is received from the camping cell.
17. The method of claim 1, wherein each CG resource configuration of the list of CG resource configurations associated with the list of cells is further associated with a version number.
18. The method of claim 17, wherein the validation condition further comprises whether the CG configuration of the camping cell is valid according to the version number.
